Question: 2 30 pts a cubeshaped solid block with unknown density...
2. (30 pts) A cube-shaped solid block with unknown density is placed in a water tank. The length
of one side of the cube is 0.4 m. The cube is attached to the bottom of the tank with a cable, and
the tensile force in the cable is measured. A 0.1 m high portion of the cube extends above the
water surface, with the remaining 0.3 m submerged. If the tensile force on the cable is 100 N,
what is the density of the block?
